Awkward night led to lame text?

So I was dating/seeing this guy. The night before I stayed at his place...and we did the deed and it was awkward and I got slightly upset about the progression of our dating. I was going to leave him alone.--He is rather insensitive and unemotional. The next morning when I left for work, I said bye and did not hear from him till 9 in the evening. I fell asleep early from all the long nights and when I saw the text this morning it said "hi hi hi" How do I respond to that? I thought he would mention something about how awkward it was?
